2 Claims.

My invention relates to a combined heating and cooling system and relates particularly to a furnace for heating two different liquids, one of which is employed to furnish hot water and the other of which is used in conjunction with a cooling unit. 7

Heretofore, it has been customary to employ a bucket-a-day furnace for heating water which is used in the kitchen or bathroom. The bucketa-day furnace is economical in the consumption of coal or like fuel. Attempts have been made to utilize a single heater or furnace wherein heat may be supplied for the premises in winter and the same heater may be used in summer for air conditioning the premises. Expensive equipment is necessary to utilize the above systems.

Therefore, it is an object of my invention to construct a furnace which will economically heat two different liquids for the purposes heretofore described.

Another object of my invention is to employ a single heating unit which will heat water and which, also, will heat a liquid that produces a.

refrigerating effect.

Another object of my invention is to construct a furnace having two compartments, for two liquids, which surround the fire chamber.

Another object of my invention is to provide an improved device of the character described, that is easily and economically produced, that is sturdy in construction and which possesses a maximum degree of efficiency and of accuracy.

With the above and related objects in view, my invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawing, in which:

Fig. 1 is a fragmentary sectional View of a furnace and its connection with a household absorption type of refrigerator as well as a hot water storage tank.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1.

Referring now in detail to the drawing, I disclose in Fig. 1 a fragmentary sectional View of a bucket-a-day furnace, generally designated as A.

The furnace A has an outer casing ID of metal which is cylindrical in form with the customary openings (not shown) therein for the removal of ashes and for the pouring of coal upon a grate designated as I2, the latter being spaced from the floor of the furnace.

Integrally formed with the outer casing H1 is an inner cylindrical metallic wall [4 which is formed with an opening therein through which coal is inserted.

The walls I and 14 are united by a series of short horizontal walls l6, l 8, and 20. The walls l6 and i8 are closer to one another than the walls l8 and 28. Thus the walls H3, l4, l6 and I2 form a small reservoir 22 and the walls in, M, l8 and 2B form another reservoir 24. The upper reservoir 22, for holding a solution of ammonia water, is smaller than the lower reservoir 24 which re tains water.

An absorption or gas fired type of refrigerator B of the type generally placed on the market under the trade name Electrolux has a supply or lead conduit 26 and a return conduit 28 connected to the reservoir 22 wherein the aqua ammonia solution is retained. The tubes 30, 32, leading from the reservoir 24, are connected to a hot water tank, generally designated as C.

The fuel within the furnace, designated as 34, is placed so that it is on the level with the vertical center of the ammonia reservoir 22. It is necessary to have the fuel bed at the height hereinabove set forth in order to secure the most efficient application of heat-with the application of heat, ammonia vapor is driven off from the aqua ammonia solution. If the fuel bed should be lower than the height indicated, insufficient heat for vaporizing the ammonia will be emitted by the burning fuel, which may be pea coal, coke, or bituminous coal.

A recapitulationof theoperation of my invention is as follows:

The furnace having a water reservoir 24 and an ammonia reservoir 22 has the ammonia reservoir suitably connected to a gas-fired type of refrigerator B. Suitable stop and drain valves as well as an indicator whereby the height of the liquid is seen also may be included in the circuit. The water reservoir 24 is suitably connected to a hot water tank C. The ignited fuel is built to a height which reaches to the middle of the ammonia reservoir 22, whereby the same fuel bed supplies heated water for household use as well as refrigeration.

Although I have not shown the details of the various connections by which the lead conduits as well as the return conduits are united to the various parts, it is within the scope of the average mechanic to make the necessary connections.

Although my invention has been described in considerable detail, such description is intended as illustrative rather than limiting, since the in-.

V vention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention: 1. In combination a furnace, an absorption beingin alignment with'the'absorbent medium said grate forming a fire pot adapted for the combustion of a solid fuel, pipes connecting said refrigerator to said absorbent medium chamber, and

Water tank.

chamber, the inner walls of said chambers and pipes connecting said water jacket tosaid hot 2. In combination a'furnace, an absorption type of refrigerator, and a hot water'tank, said furnace having a chamber wherein water may be, 5 heated, means for distributing heated water from said chamber to said hot water tank, said furnace having an absorbent medium chamber in alignment with said water chamber, means for transferring the absorbent medium from its chamber 10 to said refrigerator, and the inner walls of said v chambers and said grate forming a fire pot wherein solid fuel may be consumed.
